An Improved Recycling Folded Cascode OTA with positive feedback
In the literature, Improved Recycling Folded Cascode (IRFC) Operational Transconductance Amplifier (OTA) is proposed for enhancing the DC gain and the Unity Gain Bandwidth (UGB) of the Recycling Folded Cascode (RFC) OTA. In this paper, an enhanced IRFC (EIRFC) OTA which uses positive feedback at the cascode node is proposed for enhancing the differential mode (DM) gain without changing the unit...
متن کاملDesign and Analysis of Gain Boosted Recycling Folded Cascode OTA
In this paper, a low Power, Gain Boosted Recycling Folded Cascode Operational Transconductance Amplifier (GB-RFC OTA) is described. The proposed GB-RFC OTA is designed using 130nm CMOS technology and achieves enhanced gain, unity gain bandwidth and slew rate with the low Power budget. The proposed circuit operates on 1V supply voltage and 200 μA bias current and consumes a power of 798μW.The GB...
